Apr-23-10  eykca: I think some of the finest sacrifeces are those that even the 1500 player could find yet were great enough to down a master. This sac clearly falls into that category. Gives all us 1500s a little hope ;)

  patzer2: The demolition sacrifice 23. Bxf7+! gives Nievergelt a winning attack.

Nievergelt was probably not a club player, as suggested by his strong result, reported at http://www.olimpbase.org/1954q/1954..., in a 1954 international tournament in Switzerland where he placed second ahead of two GMs and four IMs.

Apr-23-10  ounos: 20. ...hxg5 seems dubious.
Apr-23-10  RandomVisitor: 23.Rh3 also seems to win.
Apr-23-10  mpl: 23. ♗xf7 is probably not the best move. After 23.. ♔f8! Δ ♗c5, ♕xf7 it's a long way to go for white...

Without sacrifice white could win with 23. ♖h3! . For example: 23. ♖h3! ♗c5+ 24. ♔h2 ♗d5 25. ♕h5 ♔f8 26. f6

  Chessmensch: Deep Fritz 12 fully agrees with <mpl>'s assessment noting also that capturing the bishop with the king is much worse than Kf8.

  kevin86: White's attack along the h-file is irresistable!

  watwinc: Kf8 still looks unpleasant after 24 Rd8:+ Rd8:, 25 g6 - say, Bc5+ 26 Kh2 Be8 27 f6.

  Phony Benoni: It would have been an even better pun had William Winter been playing Black.
Apr-23-10  drpoundsign: I always thought the line was "x ray light in To NITE.." making the Metallica standard about nuclear war.

  chrisowen: Nievergelt's immortal? Money for old rope? Which is it you decide. 6.Bc4 is Fischer Sozin, the wizard Bobby sets out back in the 50s to popularize it. Freeing the bishop looks to house the queen's landing space with check. Erwin the hunter crocks the black kingslide, script is his majesty is hung out to dry. 20..Nxe4 Nxe4 peter's out with slight advantage to white ..hxg5 and the noose is around his neck hook line and sinker chief.
